Drug Information
5 reviews for Ketoconazole (Nizoral)
Nizoral contains Ketoconazole.
Ketoconazole tablets are an antifungal medicine taken by mouth. Because they can cause serious liver damage, they are only used for serious fungal infections when other antifungal medicines cannot be used.
In some countries, ketoconazole tablets are also used by specialists to treat Cushing's syndrome (too much of the hormone cortisol). For skin and scalp problems, ketoconazole creams and shampoos are much safer.
What is it used for?
- Serious fungal infections when other treatments are not suitable
- Cushing's syndrome, under specialist care in some countries
How does it work?
Ketoconazole stops fungi from making ergosterol, a building block of their cell walls. Without it, the fungus cannot grow.

Like all medicines, Nizoral can cause side effects, but not everybody gets them.
Common side effects

These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Yellowing of the skin or eyes, dark urine, pale stools, or unusual tiredness (liver damage)
- A fast or uneven heartbeat, or fainting
- Severe tiredness, dizziness and weakness (possible low hormone levels)
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Take it once a day, with food, exactly as your doctor tells you.
- A common adult dose is 200 mg once a day, increased to 400 mg in some cases.
- Go to all your blood tests.
- Do not stop taking it before your doctor tells you, or the infection may come back.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Never take two doses at once.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
